Description:

TECHNICAL FIELD

[0001] The present invention relates to charcoal grills. More
particularly, this invention relates to a portable charcoal grill that
vertically fixes charcoal to the internal support mesh by fixing strings
in such a way that the middle portion of each fixing string is fixed to
the internal support mesh and both ends of the fixing string are extended
through the through-hole of the charcoal and then widened and bent
horizontally at the upper end of the charcoal, so that the bent fixing
string supports the wire roasting mesh and objects to be roasted.
Therefore, the portable charcoal grill does not require any additional
mesh to fix the charcoal to the internal support mesh. The height of
portable charcoal grill can be reduced and this can prevent structural
damage from occurring during loading, storing, or carrying.

BACKGROUND ART

[0002] Conventional portable charcoal grills, as shown in FIGS. 1 and 2,
are configured to include: a housing 2 whose side walls incline and widen
at toward the top; an internal support mesh 10 having a side wall support
mesh 11-1, supported by the side walls of the housing 2, and a lower
support mesh 11, placed at the bottom of the housing 2, for supporting
charcoal 4; a charcoal fixing mesh 5 for covering and placing the
charcoal 4 on the lower support mesh 11; and a wire roasting mesh 3 that
is placed on the upper end of the side wall support mesh 11-1 and forms a
chamber thereunder between itself and the charcoal fixing mesh 5.

[0003] The housing 2 has a side wall 1 whose end forms a bent band 9 that
is bent to support the edge of the wire roasting mesh 3. Ignition
material 12 for igniting the charcoal 4 is placed between the lower
support mesh 11 and the internal bottom surface of the housing 2. The
charcoal support mesh 5 and the internal support mesh 10 are securely
coupled to each other by a coupling member 13.

[0004] The side wall 1 of the housing 2 is inclined. The side wall support
mesh 11-1 of the internal support mesh 10 is supported by the inclined
side wall 1. Since the side wall 1 is made of a soft material, however,
it does not attach the internal support mesh 10 at a certain location and
instead is bent. This is problematic since the igniting material 12 is
not easily inserted to the chamber. In particular, when the igniting
material is inserted, the charcoal fixing mesh 5 must be moved, which
accordingly causes the charcoal 4 to move.

[0006] The conventional charcoal grill is configured in such a way that a
spacing maintaining mesh 40 is placed at the center portion of the
charcoal grill; internal support meshes 20 are placed at both sides of
the spacing maintaining mesh 40; ignition materials 12 are placed under
the respective internal support meshes 20; and charcoal 4 is placed on
the respective internal support meshes 20 and arranged in a plurality of
columns (or rows), spaced from each other at a certain interval by
charcoal fixing meshes 30. The charcoal fixing mesh 30 is formed in such
a way that: a side support part 33 and an upper support part 32 which are
bent to receive and fix charcoal in a plurality of columns; interval
maintaining downward-protruding parts 35, whose bent height is similar to
half of the charcoal height, for maintaining a interval between the
columns of the charcoal; and protrusions 34 that are extended from the
interval maintaining downward-protruding parts 35, i.e., the upper
portion of the columns of the charcoal placed at the center portion, to a
wire roasting mesh 3.

[0007] FIG. 4 is a cross-sectional view illustrating the charcoal grill,
taken along line G-G, in FIG. 3.

[0008] As shown in FIG. 4, the internal support mesh 20 is placed on the
bottom surface of the charcoal grill. The charcoal 4 are placed on the
internal support mesh 20 in columns spaced apart from each other at a
certain distance. A side support part 33 and an upper support part 32 are
bent to receive and fix charcoal in a plurality of columns. Interval
maintaining down-protruding parts 35 separate the columns of the charcoal
4 at a certain distance. Protrusions 34 are shaped to cover the upper
part of the charcoal placed at the center portion and are extended from
the interval maintaining downward-protruding parts 35 to the vertical
direction.

[0009] FIG. 5 is a cross-sectional view illustrating the charcoal grill,
taken along line H-H, in FIG. 3.

[0010] As shown in FIG. 5, an internal support mesh 20 is placed and
supported between interval maintaining meshes 40. Ignition material 12 is
placed in the internal support mesh 20. The internal support mesh 20 is
placed on the side wall of the housing 2. The side wall of the housing 2
forms an opening 6. Charcoal 4 are placed on the internal support mesh 20
and placed upright at a certain height. The protrusions 34 wrap the sides
of the charcoal 4 and at the same time support the wire roasting mesh 3.

[0011] Since the charcoal fixing mesh 30 is supported by the spacing
maintaining meshes 40 which are separated from each other, all members
are tightly assembled and charcoal is not moved. Since the charcoal is
placed and arranged in columns in the housing, the conventional charcoal
grill is advantageous to a roast item that needs to be cooked by
relatively even heat. As shown in FIG. 4, the columns of charcoal 4 are
arranged at a certain distance by the interval maintaining
downward-protruding parts 35. Also, the charcoal fixing mesh 30 is formed
to include protrusions 34 that extend upward from the columns of
charcoal, placed at the center of the columns, to the wire roasting mesh
3. The protrusions 34 form protruding means for supporting the wire
roasting mesh 3.

[0012] However, since the conventional charcoal grill is configured in
such a way that its meshes are coupled to each other, its volume, height
and width, increases and accordingly this causes an increase in
manufacturing costs as well as an increase in freight charges and storage
fees.

[0013] In addition, since the ignition material is placed in the bottom of
the housing and then ignited, air cannot be continuously provided to the
ignition material and accordingly the charcoal cannot burn evenly.

[0014] Furthermore, since the housing containing charcoal and meshes is
made of relatively thin aluminum and accordingly suffers from vertical
weakness, its shape can be distorted during movement and this breaks down
the arrangement of the charcoal and lowers the product price.

Advantageous Effects

[0029] As described above, the present invention has the following
advantages.

[0030] In accordance with a first aspect of the present invention, since
the portable charcoal grill fixes charcoal to the mesh through the
through-hole of each charcoal, the charcoal fixing work can be easily
performed without any malfunction.

[0031] In accordance with a second aspect of the present invention, since
the portable charcoal grill fixes the charcoal to the mesh and supports
the wire roasting mesh by the pillars each of which is cut as a band-type
from the internal support mesh, it does not require any additional

the portable charcoal grill places an additional charcoal fixing mesh
located above the internal support mesh, in which the charcoal fixing
mesh forms interval maintaining upwardly-protruding parts for maintaining
the interval between the charcoal and supports the wire roasting mesh,
the portable charcoal grill can be easily loaded with charcoal and easily
assembled with others.

[0035] Also, since the portable charcoal grill includes an ignition
material support mesh in an charcoal underside space formed by the space
forming legs located at both sides of the internal support mesh so that
the ignition support mesh supports the ignition material and has passages
for providing outside air above and below the ignition material, the
ignition material can be easily ignited and continuously burned.

[0036] In addition, since the portable charcoal grill repeatedly forms
bent grooves on the side wall of the housing at a certain distance, it
can increase the vertical strength of the side wall and thus enhance
storage convenience, loading convenience, and durability to prevent
structural damage.

[0037] Furthermore, since the portable charcoal grill forms a pushing
portion that protrudes downwards at the middle portion of the internal
support mesh, the pushing portion prevents the ignition material from

[0079] The portable charcoal grill, according to the present invention,
places charcoal on an internal support mesh located at the bottom of the
housing thereof. The portable charcoal grill includes: a fixing string 50
having a certain length whose lower end forms a middle bent portion 53
that is vertically fitted into part of the internal support mesh 20 at
which the charcoal is placed, and whose upper end is widened to fix the
charcoal; charcoal 4 each of which has a through-hole 4-1 through which
the fixing string 50 is extended and has a height such that the fixing
string 50 protrudes from top thereof; and a wire roasting mesh 3 placed
on the fixed charcoal 4.

[0080] The internal support mesh 20 includes: a side support part 23 that
is bent at the ends of the portion holding up the charcoal 4 and blocks
the sides of the charcoal located close to the ends; and interval
maintaining parts 22, located at the upper end of the side support part
23, for maintaining a certain interval between the side support 23 and a
side wall or other side support parts.

[0081] The portable charcoal grill, according to the present invention,
further includes space forming legs 24 for forming a space between the
side support part 23 and the portion holding up the charcoal 4 of the
internal support mesh 20. An ignition material is fitted into the space
and the space forming legs 24 extend downwards.

[0082] The fixing string 50 has a certain length and is bent at the middle
length thereof, so that the middle bent portion 53 is formed at the
middle length of the fixing string 50 and a first string 51 and a second
string 52 are formed with respect to the middle bent portion 53. The
first and second strings 50 and 51 are inserted into the through-hole 4-1
of the charcoal 4 and both upper ends of the first and second strings 50
and 51 are bent to secure the upper end of the charcoal 4.

[0083] The portable charcoal grill, according to the present invention,
further includes at least four vertical bar-type pillars 60, whose lower
ends are fixed to the internal support mesh 20, for supporting the wire
roasting mesh 3. The vertical bar-type pillars 60 form a space between
the upper end of the charcoal and the wire roasting mesh 3.

[0084] The vertical bar-type pillars form a horizontal bar 61 at their
upper end to support the wire roasting mesh 3. The lower end of each of
the vertical bar-type pillars 60 is spot-welded or bound to the internal
support mesh. Each pillar 60 has a middle bent portion 62 that is fixed
to the internal support mesh 20 by a wire. As shown in FIG. 9, the
internal support 20 is processed to form a pillar 60 and a fixing string
50 as parts of the internal support 20 are cut as a band-type and
vertically bent upwards to match the interval of the arrangement of the
charcoal. The upper end of the pillar 60 forms a horizontal bar 61 to
receive the weight of the wire roasting mesh 3. The horizontal bar 61 can
be integrally formed with the pillar 60. In addition, the horizontal bar
61 may be individually manufactured and then coupled to the pillar 60.

[0085] As shown in FIGS. 6 and 7, the middle bent portion 53 of the fixing
string 50 is fixed into the internal support mesh 20 at which the
charcoal is placed. Fixing the middle bent portion 53 to the internal
bent support mesh 20 is performed by a welding method, a bonding method,
or an additional wire. Also, the middle bent portion 53 can be fixed to
the internal middle bent portion 53 in such a way that it is twisted and
turned. The first and second strings 51 and 52 of the fixed fixing string
50 are extended through the hole of the charcoal 4 as shown in the left
diagram of FIG. 7.

[0086] After that, the first and second strings 51 and 52 are widened at
and then bent over the upper end of the charcoal 4 to fix it. The first
and second strings 51 and 52 may be bent to cover the outer side of the
charcoal 4 as occasion demands. The fixing string 50 including the first
and second strings 51 and 52 is made of various materials, such as iron
or aluminum.

[0087] That is, the upper end of the charcoal 4 is fixed by the first and
second strings 51 and 52 of the fixing string 50 whose lower end (middle
bent portion 53) is fixed to the internal support mesh 20, and thus the
charcoal 4 is tightly fixed and placed on the internal support mesh 20.
Therefore, the portable charcoal grill of the present invention does not
require any additional fixing mesh.

[0088] Also, the portable charcoal grill of the present invention does not
need an additional space maintaining mesh, which makes it possible to
reduce the height and width of the grill. Therefore, the freight charge
and storage fee for the portable charcoal grill can be reduced and the
grill provides a convenient operating method for users. However, it can
exert the same function as a conventional grill.

[0089] FIG. 10 is a cross-sectional view depicting a third embodiment of
the portable charcoal grill according to the present invention. FIG. 11
is a cross-sectional view depicting an exemplary example modified from
the third embodiment of FIG. 10.

[0090] As shown in FIGS. 10 and 11, the third embodiment of the portable
charcoal grill is configured in such a way that an internal support mesh
is placed on the bottom of the housing and supports the charcoal. Like
the first embodiment, the third embodiment has also the fixing string 50,
charcoal 4 and wire roasting mesh 3.

[0091] The third embodiment includes: space forming legs 24 for forming a
charcoal underside space 24-1 between the internal support mesh 20 and
the bottom of the housing; and ignition material support mesh 70 for
supporting ignition material 12. The space forming legs 24 are integrally
formed with the internal support mesh 20 as both ends of the internal
support mesh 20 are bent down. The ignition material support mesh 70 is
located at half the height of the charcoal underside space 24-1 and
curved upwards at its center portion. The ignition material support mesh
70 may be formed to include: an ignition material support portion at the
center thereof; and leg-type bent portions having a certain height at
both sides thereof. The ignition material support portion may be formed
to have an upward-protruding form, i.e., an embossed shape, and thus may
provide different heights to form a space between the bottom side and the
ignition material support portion. The position of the embossed shape is
altered according to the ignition material size.

[0092] The housing 2 forms bent grooves 80 for receiving a vertical weight
on the side wall 1 at a certain distance.

[0093] Since the third embodiment is the same as the first embodiment in
terms of the method for fixing the charcoal 4 on the internal support
mesh 20 using the fixing string 50, its detail operation is omitted in
the following description except for the function of other elements. The
ignition material support mesh 70 is formed in such a way that its center
portion protrudes upwards to be located at half the height of the
charcoal underside space 24-1, in which the charcoal underside space 24-1
is formed by the space forming legs 24 between the internal support mesh
20 and the bottom of the housing. The ignition material support mesh 70
supports the ignition material 12 so that there is air circulating around
the ignition material 12, i.e., there is as space above and below the
ignition material 12. Therefore, the ignition material 12 can be easily
ignited, thereby reducing the ignition time, and it does not extinguish
during burning.

[0094] The housing 2 forms bent grooves 80 for receiving a vertical weight
on the side wall 1 at a certain interval, so that the housing 2 can
maintain its original form when objects to be roasted are loaded or
roasted. The internal support mesh 20 forms a pushing portion 25 that
protrudes downwards at the center thereof. The pushing portion 25
maintains charcoal at a certain location, so that the charcoal can be
evenly ignited.

[0095] FIG. 12 is a cross-sectional view depicting a fourth embodiment of
the portable charcoal grill according to the present invention. FIG. 13
is a cross-sectional view depicting an exemplary example modified from
the fourth embodiment of FIG. 12.

[0096] As shown in FIGS. 12 and 13, the fourth embodiment of the portable
charcoal grill is configured in such a way that an internal support mesh
is placed on the bottom of the housing and supports the charcoal. Like
the third embodiment, the fourth embodiment has also the internal support
mesh 20 and the ignition material support mesh 70.

[0097] The fourth embodiment is configured to include a charcoal fixing
mesh 30 that covers charcoal 4. The charcoal fixing mesh 30 is formed in
such a way that interval maintaining downward-protruding parts 35 are
bent down to separate and maintain an interval between the charcoal 4.
The wire roasting mesh 3 is placed on the charcoal fixing mesh 30. This
structure reduces the height of the housing of the fourth embodiment.

[0098] The housing 2 forms bent grooves 80 for receiving a vertical weight
on the side wall 1 at a certain distance.

[0099] Since the fourth embodiment is configured in such a way that the
wire roasting mesh 3 is placed on the charcoal fixing mesh 30 that covers
charcoal 4, it can reduce its entire height while also increasing the
load amount of charcoal. Therefore, the fourth embodiment can reduce the
freight charge and storage fee of the grill.

[0100] Also, since the ignition material support mesh 70 is located under
the internal support mesh 20 so that the ignition material 12 placed on
the ignition material support mesh 70 is located at the middle of the
height between the bottom of the housing 2 and the internal support mesh
20, the ignition material 12 is completely burned by air circulating
above and below the ignition material 12, thereby increase the burning
efficiency. That is, the ignition material 12 is not extinguished when it
is lit and provides even heat to the object to be roasted.

[0101] The internal support mesh 20 forms a pushing portion 25 that
protrudes downwards at the center thereof. The pushing portion 25
maintains charcoal at a certain location, so that the charcoal can be
evenly ignited.

[0102] FIG. 14 is a cross-sectional view depicting a fifth embodiment of
the portable charcoal grill according to the present invention. FIG. 15
is a cross-sectional view depicting an exemplary example modified from
the fifth embodiment of FIG. 14.

[0103] As show in FIGS. 14 and 15, the fifth embodiment of the portable
charcoal grill is configured in such a way that an internal support mesh
is placed on the bottom of the housing and supports the charcoal. The
fourth embodiment includes the same elements as the fourth embodiment and
further includes a charcoal fixing mesh 30 that supports charcoal 4. The
charcoal fixing mesh 30 is formed in such a way that interval maintaining
upward-protruding parts 36 are bent upwards to separate and maintain an
interval between the charcoal 4.

[0104] Since the fourth embodiment is configured in such a way to place
the charcoal 4 loaded with the charcoal fixing mesh 30 on the internal
support mesh 20, it is easy to assemble the elements. Also, since the
wire roasting mesh 3 is directly placed on the charcoal fixing mesh 30,
the entire height of the fourth embodiment is decreased and thus the
freight fee and storage fee can also be reduced.

[0105] Also, since the ignition material support mesh 70 is located under
the internal support mesh 20 so that the ignition material 12 placed on
the ignition material support mesh 70 is located at the middle of the
height between the bottom of the housing 2 and the internal support mesh
20, the ignition material 12 is completely burn by air circulating above
and below the ignition material 12, thereby increase the burning
efficiency. That is, the ignition material 12 is not extinguished when it
is lit and provides even heat to the object to be roasted.

[0106] The internal support mesh 20 forms a pushing portion 25 that
protrudes downwards at the center thereof. The pushing portion 25
maintains charcoal at a certain location, so that the charcoal can be
evenly ignited.

[0107] Although the preferred embodiments of the present invention have
been disclosed for illustrative purposes, those skilled in the art will
appreciate that various modifications, additions and substitutions are
possible, without departing from the scope and spirit of the invention as
disclosed in the accompanying claims.
